我有一個音頻文件從服務器下載到我的文檔目錄。我試圖用AVPlayer播放相同的內容,但有些原因無法完成。以下是我的整個代碼。如果我們onlineResource
取代localAudioPath
它起着罰款AVPlayer播放在線資源,但不是相同的下載資源
import UIKit
import AVFoundation
class AudioController: UIViewController {
var player : AVPlayer!
override func viewDidLoad() {
super.viewDidLoad()
}
@IBAction func playAudio(sender: AnyObject) {
var name = "bell.mp3"
var docs = NSSearchPathForDirectoriesInDomains(directory, .UserDomainMask, true)[0] as! String
var localAudioPath = docs.stringByAppendingPathComponent(name)
var onlineResource = "path/to/online/bell.mp3"
if NSFileManager.defaultManager().fileExistsAtPath(localAudioPath!) {
let playerItem = AVPlayerItem(URL: NSURL(string: localAudioPath!)!)
player = AVPlayer(playerItem: playerItem)
player.play()
} else {
/* Alamo fire code to download file to docs directory*/
let destination = Request.suggestedDownloadDestination(directory: .DocumentDirectory, domain: .UserDomainMask)
Alamofire.download(.GET, NSURL(string: audio.audioUrl)!.http, destination)
.progress { (bytesRead, totalBytesRead, totalBytesExpectedToRead) in
println(totalBytesRead)
}
.response { (request, response, _, error) in
println(response)
}
}
}
}
有人能告訴我,如果它甚至有可能發揮使用AVPlayer本地文件?
